It is 81 blocks, 9 by 9.
I made each block with scraps from my 1 1/2 inch scrap bin--which is greatly reduced but still has several quilts in it. The scraps include many of my mother's. The solids were also in my stash as small yardage pieces.
I sew them together in 2s, then 4s, then 8. I press to one side and nest the 8 rows together into a block.
I put the quilt together into nine sections of nine blocks each.
Then, put these together in sections, leaving only one long seam that goes for the whole 9 block length.
